Procurement Notes

Verify the specific suffix against the manufacturer's datasheet to confirm packaging details such as reel or cut tape quantities. Ensure the ordering code matches the required impedance and current ratings for the target circuit design. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when space constraints require a compact filter solution for high-speed differential signals. Evaluate the 400 mA current rating against the operational load to prevent saturation. Consider the 300 Ohm impedance profile for effective noise suppression at 100 MHz without significantly attenuating the desired signal bandwidth.

Part Context

This part belongs to the TDK ACM series of chip-type common mode filters. The series is characterized by its small footprint and suitability for portable electronic devices where board real estate is limited. It serves as a passive component for electromagnetic interference mitigation in data transmission interfaces.

Replacement Considerations

Consult official substitution lists for compatible parts with matching impedance and current ratings. Verify pin compatibility and thermal performance before integrating alternative components into the existing layout.
